To all whom it may concern." 1 1 i Be it known that we, FRANKLINGEORGE NEUBERTH and ERNEST MYRON Gmrmnr, citizens ofthe United States, residing said Nnoisnn'rrr at Ansonia, and said Giannini: at Waterbury, county of New Haven, and State of Connecticut, haveinvented certain new and useful Improvements in Pipe- Covers, of which the followingisa specifi cation. Our invention relates to improvements in pipe covers for smokers pipes,and the object of our improvement is toproduce a cover structure in which thecover proper is mounted so that it may be readily swung back and forth between the position of use or closed position and the open position, without being moved bodily as a whole relatively to the bowl of thepipe, andfwhich has spring means for being held in either the open or closed position,as desired, and which, furthermore, 1 is adapted, without change, for use with pipes of difl'erentsizes, both as to the dimensions of the bowl and thethickness' of the wall." In the accompanying drawing 1 F gure 1 is aside elevation of a smokers pipe that is providedwith one 'ofourim proved pipe covers; t

Our improved pipe cover structure comprises a cover proper 10 of suitable size and form to fit over and cover the opening of the bowl 11 of the pipe 12 with which it is to be used and also comprises a spring Specification of Iietters Patent.

structure 13 of peculiar and special form that serves to hold the pipe cover structure inpperative position on the said bowl l1 and also serves as spring means for resiliently holding the said cover proper 10' in whatever position it may be set, particularly, to holdthe cover proper in either the open or the closed position. 1 The cover properlO comprises a circular body portion 1 1 that isfcomposed of a flat portion 151 that fits over the top Wall ofthe bowl 11 anda middle portion 16 of convex form that is provided with a plurality of vent holes 17 On the front side the ri1n15 isbent upwardly to provide a tip- 18 that serves as ahandle for conveniencein opening the cover. 1 p F Onthe rear side, opposite the handle 18, thematerialof the ri1n15 is extended rear wardly in the formof a tail that is composed of the connecting neck 19 adjacent the rim 15 a pair of pintles 20 that extend laterally from the edges of outer end portio'nio'f the neck 19, one on eachside and opposite one to the other; and a short tail orwing21extending outwardly from the pintles 20 and of substantially the same widthas the connecting neck 19. Ap'air of radialjcorrugations 22 are provided extending across the rim 15 positioned one on eachside of the portion of the rim 15to which the neck 19 is con- Ii'ected, which serve to provide grooves on the under side of the rim 15 for housing portions of the spring structure 13.

Tlhe cover 10 is preferably made of sheet stee a #Thepintles 20' serve as thebearing memhers for the cover 10, being operatively housedin the circularloop portions 23 of the springstrueture 13. The wing 21 serves in cocperation with the loops 23 as the positioning means for the cover 10by having its lateral edge portions in bearing engagement with the material of the said loops 23.

The spring structure 13 is a symmetrical structure, formed of a single piece of wire as follows :The end portions 24 are in the form of dependent arms, suitable for extending downwardly within the bowl 11 and serving as spring arms in bearing engagement with the inner face of the side wall of the said bowl 11; the middle portion 25 1 1 1 Patented Aug. 5, 1919. Applicationfiled April 4, leis. seriaino. 287,645. 1 1

is in the form of a clependei'itiarm of'U shape, suitable for engaging'with the outer face of the side wall of the bowl 11 and cooperating with the armsQ- L for holding the cover structure in position-on t-he pipe.

At the upper end of each of the individual spring arms 2% is a rearwardly directed bar 26 that extends radially across the top edge of the side wall of the bowl 11, the two bars 26' being in registration with the grooves of the corrugations 22 when the cover 10 is in. 7 closed position and thereby serving to poas means for resiliently holding the cover in any position in which it may be set.

In the modified form of structure shown in Fig. 6 there is provided a snap movement, whereby the cover 10 is held resiliently and positively in either the open or the closed po-j sition, no provision being made for holding in intermediate positions, and in the following manner:

The 'cover- 10 differs from the cover 10 already described in the omission of the friction tail or wing 21, and in lieu thereof there is provided a spring member 28 for frictionally bearing against the part 29 of the neck 19 that is positioned between the pintles 20, the parts i being constructed and arranged so that the cover 10 is resiliently held eitherin the closed position or the open position as the case may be.

' As shown, the spring member 28 is integral with the wire of the spring structure 13 constituting the middle portion thereof, being in theform of a return bend. Thus the outer portion of the spring structure 13 is generally of W-shape, comprising two individual and relatively narrow U-shaped anddownwardly directed clampingarms 25 for engaging with the side wall of the bowl 11, and the relatively narrow, upwardly directed spring arm 28, also of U-shape.

1 the wall of thepipe bowl, and resilient positioning means for positioning the cover in different positions:

The particular structure described is a cover for a smokers pipe. A structure made on similar lines and involving similar principles of operation, with a proper change in dimensions of theparts may be used for othe purposes, as, for instance, for a cover for milk bottles and the like.

I We claiin as our invention: 7' -1. In a pipe cover structure, a cover proper and a supporting device therefor, and the said supporting device being in the form of a single piece of wire, the parts beingconstructed and arranged so that the said piece of wireserves to provide a pair of bearings for the cover, to provide spring clamping arms for engaging with the side wall of the bowl of a pipe, and also to provide means for resiliently positioning the said cover relatively toth'e supporting device.

2. In combination, a receptacle having side walls bordering an opening and a cover structure for covering the said opening, the said. cover structure comprising a cover proper and a supportin device therefor, the said supporting device Iaeing in the form of a single piece of wire that is formed so as to provide a pair of bearings for the said cover proper, spring clamping arms for engaging with the said side walls, and also means for resiliently engaging with the said cover proper fOr positioning thereof in different positions.

'3.'A pipe cover structure comprising a cover structure formed of sheet material and a frame structure formed of wire, the said cover structure comprising in one piece a cover proper, an extension at the rear thereof, and a pair, of pintles on the said extension,thesaid frame structure comprising a pair of bearings for the said pintles, a pair of spring, arms for engaging with a supporting wall, and spring positioning means for engaging with the said extension, and the said wire of which the frame structure is formed being in the form of a single piece.
